Take the Guesswork out of Vulnerability Assessment

Get the Power of Tenable Research Behind You

Our research team works closely with the security community to discover new vulnerabilities and provide insights into published vulnerabilities to help organizations quickly detect them in their environment. Our research team builds these insights into Nessus to help you become a vulnerability assessment expert (without actually having to be one).

More than 100 zero-day vulnerabilities discovered over the past 3 years

New plugins released within 24 hours of vulnerability disclosure (on average)

Plugins are automatically updated in Nessus in real-time, providing you with timely information on the latest vulnerabilities and malware, a simple set of remediation actions, and a fast and easy way to see if your systems are vulnerable. This means more comprehensive assessments and less time required to research, validate and prioritize issues.

Built For Practitioners, By Practitioners

Nessus was built from the ground-up with a deep understanding of how security practitioners work. Every feature in Nessus is designed to make vulnerability assessment simple, easy and intuitive. The result: less time and effort to assess, prioritize, and remediate issues.

Pre-Built Policies and Templates

Out of the box, pre-configured templates are included for a range of IT and mobile assets - from configuration audits to patch management effectiveness - to help you quickly understand where you have vulnerabilities. Nessus includes more than 450 compliance and configuration templates to audit configuration compliance against CIS benchmarks and other best practices.

Customizable Reporting

Easily create reports based on customized views, including specific vulnerability types, vulnerabilities by host or by plugin. Create reports in a variety of formats (HTML, csv and .nessus XML) and easily customize reports by team or client which can be emailed with every scan.

Live Results (New in Nessus 8)

Live Results automatically performs an offline vulnerability assessment with every plugin update, showing you where you may have vulnerabilities based on your scan history. From here you can easily run a scan to validate the presence of the vulnerability which accelerates the accurate detection and prioritization of issues.

Grouped View (New in Nessus 8)

Similar issues or categories of vulnerabilities are grouped together and presented in one thread, simplifying the time to research and prioritize issues for remediation. Snoozing lets you select specific issues to disappear from view for a specified period of time. So you only focus on the issues that matter at that time.
